Fork of Fork of HIV/AIDS Choropleth Map

This choropleth map visualizes the global prevalence of HIV/AIDS among adults aged 15-49 in 2017, with countries shaded from light yellow to dark red based on infection rates. The visualization uses React to render SVG paths, with d3.geoNaturalEarth1 for map projection, d3.geoPath for drawing country boundaries and graticules, and d3.scaleSequential with an interpolateYlOrRd color scale. Country codes are matched against World Atlas TopoJSON features, and missing data appears in gray. Data comes from the IHME HIV prevalence dataset.

Fork of HIV/AIDS Choropleth Map

This choropleth map visualizes the share of the population infected with HIV/AIDS for the year 2017, using a yellow-orange-red sequential color scale. Countries without data are rendered in gray, and the map includes graticules and interior boundaries for context. The visualization loads country geometries from the World Atlas TopoJSON and HIV prevalence data from a CSV file, joining them via ISO country codes. It uses d3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule`, with React managing the SVG rendering.
